And thanks to Turtledove's writing, you can find yourself in a novel full of names like "Arminius" and "Varus" and "Aristocles" and many more, and you will not get confused as to who is talking, and who they are referring to.

Though we probably should allow them an army; it just dawned to me that most successful historical leaders have won because of their skills as generals, not because they personally kicked ass (though some, like Arminius and Attila were no mean fighters themselves).
